although I'm somehow biased to suggest SGE, I also check from time to
time the Torque mailing list.

Whether any queuing system is a standard might not matter. More
important for chosing one, may be the technical points. To compare
SGE and Torque e.g.:
- Do you need support for Tight Integrated Linda (I think this will
most often mean Gaussian) (and PVM) parallel jobs: use SGE
- Do you have some special nodes inside your cluster, and you need to
specify your resource requests for a parallel job (i.e. combination
of different types of machines you need for it) in a fine granulated
manner: use Torque
It's of course impossible to know already in advance a) the needs of
all the applications, and b) all the features of the queuingsystems,
if you just start to look into queuing systems.
And I must admit: some years ago I was also shocked by the many pages
of the manuals of the queuing systems - we only wanted to submit some
jobs at that point in time. Nowadays I see many possible
enhancements, which would make the manuals even thicker.
